Type F RCCBs are designed to detect mixed frequency residual
currents 10Hz< 1kHz, associated with single phase inverter control,
used in modern domestic appliances.
Type AC and A RCCBs are designed to detect leakage currents at 50Hz.
Type F RCCBs dectect AC, A and mixed frequency leakage currents (F)
as defined in BSEN62423.
They also incorporate 3kA transient resistance and 10mS short
time delay, to reduce nuisance tripping associated with this type of load.
These devices must not be used with loads/inverters that can produce
smooth DC leakage currents - See Type BCheck the appliance installation instructions relating to RCD
protection and sensitivity. Verify if you need Type F or Type B
and the required sensitivity for the equipment.
